AEM Induction Systems is a pioneer in high-performance air intake and filtration technology, engineered to deliver maximum horsepower, torque, and efficiency. With a relentless commitment to innovation, AEM designs precision-crafted cold air intakes, short ram systems, and performance filters that optimize airflow for superior engine performance. Whether on the street or the track, AEM's dyno-tested solutions provide unrestricted power and throttle response without compromise. More air. More power. More performance.
The AEM 21-485B Performance Cold Air Intake System produces horsepower and torque gains by replacing your vehicle's restrictive factory air filter and air intake housing. This air intake system was designed, tuned and dyno-tested to fit specific Mazda RX-8 models. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air filter is located above the passenger side wheel well which is designed to reduce intake air temperature and increase horsepower. The intake tubing is comprised of series of gradually expanding inlet pipes including mandrel-bent aluminum featuring a durable blue powder coated finish. This air intake system was developed to accommodate the engine's factory emissions control devices including the mass air flow sensor and breather hoses. The cone shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). The air intake system is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards while others are 50 state legal.
